Be it known'that I, ALPHONSE F. PIEPER, a citizen of the United States, residing at Rochester, in the county of Monroev yand State of New York, have invented Vcertain new and useful Improvements in, Valves; and I do hereby declare the following to be a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming' a part of this rspecifica-tion, and to the reference numerals marked thereon.

This invention relates to valves, and more particularly to those of the multiple type, one object of the invention being to provide an efficient, self-containedv and conveniently operated valve of this variety for controlling a plurality of lluid lines.

Another object is the provision of a single,

compact valve head of the above character, adapted, forvexample, for controlling the supply of water to .dental equipment stands for the various uses thereof such as flushing the cuspidor bowl, operating the saliva ejecting means, supplying vthe drinking glass stand, and the like. v v l A further purpose is to afford such a'valve for conveniently controllingl the flow of water to lush'the cuspidor bowl either directly from the supply line oralternatively and indirectly through an aspirator device, so that the water employed-to operate the latter device may be employed alsoV toflush the cuspidor, for example, and therebyV conserve the quantity used.

To these and other ends the invention residesin certain improvements and combinations of parts all as will be hereinafterl more fully described; they novel featuresl being pointed out in the claims at theV end ot the specification.

In the drawings: o

Figure 12 is a top plan view of'a portion of the yapparatus shown in Figure j1to further illustrate the application of the invention, and f v v l Figure 18 is an yenlarged sectional detail onvthe line 13a-13a inFigure l.

Similar reference numerals throughout i f the several views indicate the same parts. VThe invention is disclosedherein, by way of illustration, as lapplied to use with av dental apparatus more fully disclosed in my 4co-pending application for patent, SerialV No. 663,892, iled September 20, 1923, for

` dental apparatus, ofwhich the present ap-` plication is a division. Such" apparatus comprisesygenerally, -a hollow arm 15,

` Figure 1, projectingfrom a suitable pedestal.

or base and having mounted Vthereonand discharging thereinto a cuspidor bowl 16, in accordance with a construction and arrangement well known in the art. Branching from and-discharging into arm 15 is a secondary armv 17 having at its upper end an enlarged portion 18 providing a .support and `housing for'the valve 19 embodying the present invention. Carried on lthe horizontal top 20 of this housing is a drinking glass holder 21 of hollow construction, the waste from which is discharged through a passage into arms 17 and 15 from which the waste and also that romthecuspidor bowl are discharged within the supporting pedestal with which a waste pipe is connected. The valve of the present invention is used to control they supply of water for flushingthe cuspidor bowl, illing the drinking glass, and operating the saliva ejecting means comprising-the flexible tube 22, the other end of which is equipped with suitable terminal forinsertion in the mouth of ythe patient. The water supply for the valve is transmitted through a pipe 23 connected with a branch of the valve head as shown and with a valve 24 carried by arm 15 and connected in the latter with a suitable water supply line carried through the supporting base.

The valve comprises preferably an integral head which may be readily manufactured as a casting, having an inlet or supply extension or branch 25, Figure 3, adjustably connected with the supply pipe 23 by means of a union connection 26. Valve b 'anch' 25 has at 27 a branch passage communicating centrally with the lower end ot an inclined chamber 2S formed centrally in the valve body. The end ot passage 2T is provided in the chamber with a .valve seat 29 with which cooperates a valve 30 to be lat-er described for controlling the supply of water to the chamber. The top ot the head is formed with a substantially cylindrical transverse enlargement 3l, Figures 2, 3 and 7, having therein a cylindrical bore 32 in which slides longitudinally a valve body having intermediate its ends a recessed portion 34. Chamber 28 has in its walls an' annular enlargement or passage 35 in the plane ot bore 82 and eut laterally into the same to provide comn'iunication between the chamber and valve bore as shown. Frach end of the bore is formed with a valve seat for cooperation with the corresponding end of the valve body 33 and 'through one of these seats 3G is a passageway 87, Figures 5 and 7, leading through the head and through a nozzle extension 3S having an upwardly projecting threaded end 39. To this connection is attached a nozzle affording a direct supply ot water tor flushing' the cuspidor. The opposite end ot valve bore 32 communicates with an internally threaded extension 40, Figures 2 and 7, in which is detachably screwed a plug 4l having an end projecting into bore 32 and provided with a valve seat 42 for cooperation with the other end of the valve body 33. rl`he outer end of the extension Ai() is closed by a threaded plug 43 Jfor access to the bore. Communicating with the extension Ll() is a passage tat, Figure 6, leading through the head to saliva ejecting means in the latter which will now be described.

The saliva ejecting means comprises preferably a substantially cylindrical, lateral enlargement 45 on the head, Figures 2 and G, formed centrally with a bore having an internally threaded end 46 opening externally and with a side of which the supply passage 1.1.4: communicates. .Bore 46 is closed at its outer end by a detachable plug 47 and its inner'portion is shouldered as at 4.8 and reduced conically to form a throat 49 as shown. A plug 50 has its head 5l screwed into bore 4G against the shoulder 4-8, the plug having a reduced tapered portion 52 extending through the throat el@ in spaced relation with the sides thereof. Flug 5() has a central passage therethrough tor the supply of water from chamber 2S by the means described to the center ot the throat. Con'nnunicating laterally with the throat is a passage leading from a downward extension iet internally threaded as at 55 tor the reception ot a nipple o6 to which is attached the flexible conductor previously described carrying the terminal for insertion in the patients mouth for withdrawing the saliva. Bore i9 communicates with a passage 5T leading through an upwardly extending threaded nozzle connection 58 having attached thereto a nozzle tube 59 discharging into the cuspidor in such an arrangement as to flush the latter. ltis apparent that this construction affords an etlicient aspirator saliva ejector' meansin the valve head, the parts of which may be conveniently reached by removal of plug di". lt is also apparent that by shitting valve body 33 longitudinally against one or the other of its cooperating seats, either the direct water supply or the saliva ejiecting means may be brought into operation, thereby flushing the cuspidor bowl, these parts being adapted for opera# tion alternately so that but one is in use at a time and the direct supply ot water cut otlLl when the ejector is in operation, to con-r serve the quantity of water necessary for continuously flushing the cuspidor. For the purpose ot p'reentingthe outward How ot water to the ejector connection, nipple 56 has termed in its inner end a valve seat 60, Figures 7 and 8, with which cooperates a check valve 6l which opens automatically when the ejector is brought into use by manipulation of the valv The valve body 33 tor selectively operating either the direct supply of water for the cuspidor or the ejector, and the valve 30 are operated by a single valve spindle 62, Figure 8, rotatably and slidably supported in chamher 28. Valve 30 is vlined on the inner end ot the spindle, so that a longitudinal sliding movement ot the latter moves this valve toward and from its seat for the purpose described. rlfhe spindle has fixed ther-eon also a hub (33 carrying a `linger rletengag ing in the recess 34 ot' valve body 83 "for shitting the latter described by partial rotation of the spindle. Means are also provided tor urging the latter toward one or the other of its extreme positions ot rotation, with the valve bot y against one or the other ot its seats, con'iprising a shoulder G5 on the hub cooperating with a spring pressed plunger 6G carried by a plug G7 `screwed'into the head.

The Vvalve spindle` 62 is rotatably supported in the head by means comprising preferably a gland cup GS in which the spindle rotates and which has a shoulder 69 bearing on an internal shoulder 70 in chams ber 28. Thesglandv cup `isilield in position by'meansv of a sleeve 71 threadedly engaged in the externally opening end of chamber-28 i and bearing against the' shoulder 5:"69 ofjth'e cup 68. Sleeve 71 supportsa'tubular'pa1t72. rotatingstherein and on the'spindle. Party '72 bears at its inner end on the'out'e'r endof the gland cup 68 and is held against longitudinal movement by inter-engaging shoulders 8V on the part andy on sleeve 1.,' Part 72 is thus free to rotate but has noy longitudinal movement and altitsinner end'carries whenevernecessary for rendering the bear.

ing of the spindle thoroughly watertight.

The outer end of part4 72 is enlarged internally and is threaded to lreceivefa'threaded CII sleeve 79 rotatably carried between a shoul der 80 and a head 81 secured to the outer end of the latter, and the sleeve carries a finger piece or ring 82 by meansrof vwhich it may be continuously rotated to thereby shift the spindle longitudinallyY independently ,ofV any rotary motion of the saine" for operating valve 80. Head 81V @arriesga` linger piece or wing 88 by means of which the spindle may be rotated independently of the longitudinal motion thereof for shifting valve bodyy 33.'

Spindle 62 thus affords ay single device hav` ing one movement in "aflongitudinal direcl tion for controllingfthe supply of waterto chamber 28 and having 'another lor rotary movement for controlling the supply of Water from .the chamber `tofthecuspidor'` directly or through the ejector-alternatively and selectively.

flhe nozzle extensions 39and '581 for' dis-k charging water into the ouspi'dor directly or through the ejector, are each provided with nozzle tubes 59 curved into parallelism with each 'other and over the cuspidor side and united in a ]o1nt"84,' Figure 13, carryil'iga common discharge nozzle85 positioned above the beginning' of a con'di'ict'ing'and distributing water-way 86 extending circumferentially about the bowl 16. These nozzle tubes 59 are connected with their respective head eX- tensions 39 and '58 bythe insertion of their lower ends into the head extensions, as shown in Figure Il. A gland nut 86;*'containing` packing 87 is provided for making these points watertight. These valve head eXtensions are also utilized, together with-the eX- tension for the glass holder nozzle hereafter described, for detachably securing the valve head to the apparatus arm 17. To this end each extension is formed below the threaded extremity thereof with a shoulder 88 carryunder side of the horizontaltop port-ion. 2O of the arm l17 and a nut 90 threadedly engaged 'with theextension detachably clamps the ,san'ie' and the valve. to the arm.'` As shown nutv90 is recessed at its upper end to avoid'interference with gland -nut'86. The supply of water for the glassholdernozzle 91 isy conducted from the supply connection u 25 of the valve head through a lateral passage 92,' FigurelQ, into a chamber 93 in which it terminates with a valve seat 94. Cooperating kwith the latter is a valve 95 operated by a spindle 96threadedly engaged*with` the walls of the valve and operated by a finger piece orknob 97. Comunicating laterally with cha1nber'93 1s a passage 98 extending. through the valve head and a threaded nozzle extension99 clamped to the end 20 of arm 17 and connected with the drinking glass nozzle 91 as described above in connection with the nozzles for the cuspidor.

The supply connection for the valve head, as already stated, is connected by a union 26 with the pipey 28 and the other end of the latter connected by a union with valve 24 which is located concentrically with the vertical axis of the end ofarm 15 andvof the cuspidor bowl. Arm 17 is rotatably secured to 15 sothat the arm 17 and the valve head and other parts carried thereby may be ing af washer 89 for engagement Vwith the adj ustedv rota-rily about the ouspidor bowl to the most convenient position. As state-d also the valve body is housed within theenlaiged portion 18 of the hollow arm 17, the half vportion or cover plate 100'of which is detachable, being secured in 'place as by means of screws 101. Access may thus be had to the valve head which is detachablyV` securedin the housing by the clam ping of its nozzle eX- tensions to the top 20 of the housing. y

In operation, finger piece 82 may be 'convenientlyV rotated to shift spindle 62 longitudinally to control admission of water to chamber 28( VBy'V turning finger piece 88 in one direction the bowl may be flushed with a direct supply of water and the supply to V the ejector ycut olf and whenever it isdesired to luse the ejector, the lingery piece is swung in the opposite'direction to admit water pressurethereto and automatically cut off the direct supply of water ltothe bowl,

which is then flushedby the dischargefrom theejector, to thereby conservethe quantity of water necessary for continuously flushing the bowl. By rotating finger piece 97 valve 95 may be seated or unseated to .cut olf or admit Water for the ydrinking glass nozzle 91. The invention thus provides a compact, self-contained, multiple valve of a practical and eliicient form of construction throughout, the parts of Which are fullyv accessible for cleaning and repair and which 1 conveniently requires the manipulation in normal use, of but two operating parts to control three supply lines, two of which are controlled alternatively by a single operating part.
